Use of the Internet has grown exponentially and adolescents are considered one of the most vulnerable groups in this new environment. Hence the problematic use of the Internet (PIU) at this stage has become a concern for a growing number of researchers. Taking into account the interest that this issue has generated at many levels, the aim of this paper is to find the prevalence of PIU among adolescents in the health area of Vigo (Spain).Cross-sectional descriptive study. The PIU validated scale was applied to children between 10 and 16 years old, captured by systematic sampling with replacement in the primary care consultations of four health centers. A descriptive and bivariate analysis was performed.The questionnaire was applaid to 165 children, 51.2% men. Problematic Internet use was observed in 38.8% (95% CI: 31.7-46.4), higher in women (46.3%) than in men (31.8%), with no significant differences (p 0.07). By age groups, the positive rate on the scale reached 36.8% in the 13-14 year range and 48.6% in the 15-16 range. The item that reached the highest score was "When I am online, I feel that time flies and hours pass without me realizing it" (60.6%).The prevalence of UPI in children / adolescents is similar to that observed in Asian adolescents. This study is the first to apply a scale validated and adapted to the Spanish cultural context in the daily practice of Primary Care consultations. Its use would allow to identify the PIU in this context and intervene if necessary.El uso de Internet ha crecido exponencialmente y los adolescentes son considerados uno de los grupos más vulnerables en este nuevo contexto. De ahí que el uso problemático de Internet (UPI) en esta etapa se haya convertido en una preocupación para un número creciente de investigadores. Teniendo en cuenta el interés que este tema ha generado en muchos niveles, el objetivo de este trabajo fue conocer la prevalencia del uso problemático de Internet entre los niños/adolescentes del área sanitaria de Vigo (España).Se realizó un estudio descriptivo transversal. Se aplicó la escala validada EUPI-a a niños entre 10 y 16 años, captados por muestreo sistemático con reposición en las consultas de atención primaria de cuatro centros de salud. Se elaboró posteriormente un análisis descriptivo y bivariante.Se entregó el cuestionario a 165 niños, de los que el 51,2% eran varones. Se objetivó un uso problemático de Internet en el 38,8% (IC 95%: 31,7-46,4), mayor en mujeres (46,3%) que en varones (31,8%), aunque no se constataron diferencias estadísticamente significativas (p=0,07). Por grupos de edad, la tasa de positivos en la escala alcanzó un 36,8% en la franja de 13-14 años y un 48,6% en la de 15-16 años. El ítem que alcanzó mayor puntuación fue “Cuando me conecto siento que el tiempo vuela y pasan las horas sin darme cuenta” (60,6%).La prevalencia de UPI en niños/adolescentes es similar a la observada en adolescentes asiáticos. Este estudio es el primero en aplicar una escala validada y adaptada al contexto cultural español en la práctica diaria de una consulta de atención primaria. Su utilización en este entorno permitiría identificar el UPI e intervenir si fuera preciso.

To determine the prevalence of psychiatric disorders in primary care pediatrics in Atlantic Galicia.An observational, descriptive, cross-sectional prevalence study was carried out in 9 outpatient clinics in A Coruña and Pontevedra with a population of 8293 children between September and November 2015. A total of 1286 randomly selected patients from 0 to 14 years of age were included. From the medical history was registered: age, sex, psychiatric diagnosis established by DSM-IV-TR criteria in its five axes, professionals who participated in the diagnosis and treatment of the process and what type of treatment was received. Authorization was obtained from the Research Ethics Committee of Galicia number 2015/427.148 of 1286 patients presented psychiatric pathology (11,5% IC 95% 9.73-13,29), 68% male. Between 0 and 5years, the prevalence was 4.5%; between 6y and 10y, 18.5% and between 11y and 14y 22%. Symptoms lasted a median of 25 months. The most frequent pathologies in 1286 patients were ADHD (5.36%), language disorders (3.42%), learning disorders (3.26%), anxiety-depressive disorders (2.4%) and behavior disorders (1.87%). Of the 148 cases, 47% had comorbidity with another mental disorder. Most of them required attention by multiple social, health and educational professionals; 33% received psychopharmacological treatment.The prevalence of psychiatric disorders in pediatric primary care is frequent, chronic and complex, increases with age and requires many health, educational and social resources.

Objective: To determine whether high levels of mid-regional pro-atrial natriuretic peptide (MR-proANP), copeptin, and procalcitonin (PCT) plasma concentrations are associated with increased mortality risk. Methods: Prospective observational study including 254 critically ill children. MR-proANP, copeptin and PCT were compared between children with high (Group A; n = 33) and low (Group B; n = 221) mortality risk, and between patients with failure of more than 1 organ (Group 1; n = 71) and less than 2 (Group 2; n = 183). Results: Median (range) of MR-proANP, copeptin, and PCT levels in group A vs B were, respectively: 209.4 (30.5–1415.8) vs. 75.0 (14.6–867.2) pmol/L (P
